How To Keep Inventory Levels Low

Why Low Inventory Levels Matter

Holding too much inventory ties up cash, increases storage costs, and raises the risk of obsolescence. Keeping inventory levels low frees up working capital, reduces waste, and improves your profit margin while still meeting customer demand.

Calculate Your Daily Inventory Cost

Understanding how much inventory you actually use each day is the foundation of a lean inventory strategy.

1. Find the total cost of goods sold (COGS) for the most recent month.
2. Divide that figure by the number of days in the month to get Daily Inventory Cost.
3. Check your current on‑hand inventory value and divide it by the Daily Inventory Cost. The result tells you how many days of supply you currently have.

Example: COGS = $30,000 for a 30‑day month → Daily Inventory Cost = $1,000. If you have $5,000 of inventory on hand, you have 5 days of supply.

Set Safe Stock Levels

Safety stock protects you from demand spikes and supplier delays.

• Lead‑time demand: Multiply Daily Inventory Cost by the number of days it takes your supplier to deliver.
• Buffer factor: Add 10‑20% extra based on how volatile your demand is.
• Review regularly: Adjust safety stock after each delivery cycle.

Collaborate with Your Supplier

Strong supplier relationships enable more flexible deliveries.

• Negotiate the smallest feasible order quantity.
• Agree on a regular delivery schedule that matches your safety‑stock calculations.
• Share your forecast so the supplier can plan production efficiently.

Industry‑Specific Tips

Retail (Fast‑Moving Consumer Goods)

• Use point‑of‑sale data to update daily demand in real time.
• Implement “just‑in‑time” replenishment for high‑turnover items.

Manufacturing (Finished Goods)

• Apply the Economic Order Quantity (EOQ) model to balance ordering and holding costs.
• Maintain a buffer of critical components rather than finished units.

E‑commerce (Dropshipping)

• Keep inventory virtually at zero by partnering with suppliers who ship directly to customers.
• Monitor lead‑time variance and adjust safety stock weekly.
